Would f/8 autofocus on the 5D be a pipe-dream? otherwise, i'm excited about what it could possibly bring... video i don't care that much about, since i barely use it now... red AF points would be nice but i have gotten use to it now! f/8 autofocus would be awesome though... sigh... doubt it will happen though. Either way, bring it on!

I bought a 1.4x in anticipation...

I had thought of getting a 1.4x in anticipation as well for use with my 100-400L but didn't pull the trigger. I was not putting too much faith in Canon delivering the firmware update as scheduled.

I've always wanted to try the 1.4 III on my 100-400, but really wanted to see the results with it on my 7d as much as my 5d3... I think it could be quite awesome for some birding and wildlife...

hmm, maybe I should "pull the trigger" on that too! Is Version III the one with the trigger?
